I have placed a few items on Ebay which might be of interest. Easy way to view is to search by my sellers name letterpres. Starts at 21.30 B.S.T. One of the items is a NOS Williams dinner plate ring. This is what any ring over 52T was knicknamed by us Brit cyclists. This ring is a 29T 1" pitch x 3/16" and is for the real go faster track man. As this one is huge there is a tiny 20T 1" x 1/8" ring for the twiddler. 60's/ 70's French tool pouch as fitted to Peugeots, Gitane and Lejeune bicycles.
Best wishes and be lucky. Michael Butler Huntingdon UK.
